Three Essays on Financial Development
Mareš, Jan ; Horváth, Roman (advisor) ; Belke, Ansgar (referee) ; Čihák, Martin (referee) ; Geršl, Adam (referee)
The dissertation is a compilation of three empirical papers on the effects of financial development. In the first paper, we examine finance's effect on long-term economic growth using Bayesian model averaging to address model uncertainty. Our global sample findings indicate that the efficiency of financial intermediation is robustly related to long-term growth. The second and third papers investigate the determinants of wealth and income inequality, capturing various economic, financial, political, institutional, and geographical factors. We reveal that finance plays a considerable role in shaping both distributions.

Wealth inequality in dynamic stochastic general equilibrium models
Troch, Tomáš ; Stráský, Josef (advisor) ; Gregor, Martin (referee)
in English In my diploma thesis I propose a dynamic stochastic general equilibrium model to describe economic inequality. The model combines two approaches that were traditionally used to model inequality - first, it features two classes of agents that differ in their ownership of capital and second, each class consists of heterogeneous agents who are subject to uninsurable idiosyncratic shocks. This combination allows the two classes to behave in a fundamentally different way while maintaining the individual character of agents in the economy - a feature that has not been modeled before but which adequately describes the empirical reality. I show that the model with classical RBC structure and a single wage underestimates the observed inequality. When the wage differential is introduced through different taxation of the two classes, the model matches empirical inequality much better. Further I argue that the government can significantly reduce inequality at a relatively small cost in terms of output lost. Finally using Theil coefficient decomposition, I show how much of the total inequality is attributable to between-class and within-class inequalities.

Global Changes in Income Distribution: Causes and Impacts
Jančovič, Pavel ; Cahlík, Tomáš (advisor) ; Břízová, Pavla (referee)
Téma bakalárskej práce: Global Changes in Income Distribution: Causes and Impacts Author: Pavel Jančovič Supervisor: doc. Ing. Tomáš Cahlík CSc. Abstract This thesis examines income inequality in the world. The main subject of investigation is the Gini coefficient, which determines the inequality. To measure the Gini coefficient are used different variables that could be empirically influencing. Econometric analysis consists of 34 countries of the world except Africa. Countries are divided into 5 groups. The measured period is between 1991 and 2011.We use the method of least squares, fixed effects and random effects. After performing regressions, results are commented, the best model is chosen, significant and non-significant variables are stated. We test models for heteroscedasticity, first order autocorrelation of the residuals and normality. Afterwards, we point out possible causes of the results. We refer to the countries in which income inequality is not a problem and reduce or stabilize Gini coefficient on low rate. Also we refer to countries, which has rate of the Gini coefficient, or income inequality increased in measured period.

Quantitative Easing and its Impact on Wealth Inequality
Lazar, Stefan-Alexandru ; Taušer, Josef (advisor) ; Čajka, Radek (referee)
The aim of this thesis is to show how the unconventional monetary policy rounds of Quantitative Easing introduced in the United States between 2008 and 2014 have led to an increase in wealth inequality. The need for the thesis arises due to the uncharted nature of QE and because of more and more information is surfacing to light which points to this connection. By analysing the distribution of these funds and adding it to the then base distribution of money supply, this study was able to determine a significant 10 % increase in the Gini Index. Furthermore it highlights how a large portion of wealth was transferred from the middle class over to the top 5 % income households. Starting from a set of assumptions the calculation is performed by extrapolating the data required and by isolating the system from any external variables. The result is a theoretical model meant to describe the mechanism that links Quantitative Easing to wealth inequality. Moreover a detailed comparison is provided with the effect of a conventional monetary policy such as Open-Market Operations. Finally solutions to this issue are being discussed from economical, political and fiscal standpoints.
